Image forming apparatus

摘要

An image forming apparatus includes a driving force transmitting mechanism transmitting a driving force from a driving source to a rotating member through a plurality of coupled driving force transmitting members. The driving force transmitting mechanism has a supporting member and a drive case. The support member supports the driving source and the rotating members. The drive case is provided on the support member and forms a closed space with the supporting member. The closed space stores the driving force transmitting members. The drive case is formed with a sound insulating part. The sound insulating part has at least either one of concave and convex parts at a position closest to the coupling part of the driving force transmitting members.

1. An image forming apparatus comprising:
a driving force transmitting mechanism transmitting a driving force from a driving source to a rotating member through a plurality of coupled driving force transmitting members,
wherein the driving force transmitting mechanism includes a support member supporting the driving source and the rotating member; and a drive case provided on the support member and forming a closed space with the support member, in which the closed space stores the driving force transmitting members and
wherein the drive case is formed with a sound insulating part at a position closest to a coupling part of the driving force transmitting members, wherein the driving force transmitting members are supported by the support member in a cantilever manner, the coupling part of the driving force transmitting members is provided in front of the support member, and wherein the sound insulating part is formed into a semispherical or polygonal pyramid concave shape protruded toward the coupling part, and wherein the sound insulating part is formed so as to face to the coupling part of the driving force transmitting members.
